I am having another problem. I think it's pressure bleed through somewhere.

There are several possibilities, the the most likely is that you installed the pressure switch from Lancair without adjusting it. If it came set for around 1000 psi, it is not enough.

If the system leaked, once up, the gear would soon sag down or cause the pump to cycle on to keep the pressure.
Let us know what happens next.
